Weird noise problem!

**GTP4** · 04-21-2009

I just finished installing my AEM wideband.
When i turn the car on, i can a hear a high pitched noise coming from the door speakers.
When i disconect the wideband , it goes away.
I got the power for the wideband from the fuse box.
Any suggestions as to what would cause this?

Ignition noise, you gotta put a suppressor on the HOT wire for the Wideband.

That or get the wideband on its own fused circuit. the tap youa re using is prolly a IGN hot that is also connected to the radio and other IGN hot circuits in your car.
